Bristol (UK): Darren Lehmann insisted it was still possible for Australia to win the Ashes despite the upheaval that led to his appointment as the new head coach of the national side.

Lehmann was brought in after South African Mickey Arthur, the first non-Australian to coach the team, was sensationally sacked 16 days before the first Test in Nottingham after several high-profile on and off-field embarrassments for the team.

These included 'homework gate', where four players were dropped from the team during Australia's 4-0 Test series loss in India this year and, more recently, the suspension of opening batsman David Warner until the first Ashes Test for a Birmingham bar-room attack on England's Joe Root following the Aussies' loss to their old foes in the Champions Trophy.

Even prior to these incidents many pundits made England, bidding for a third straight Test series win over Australia, favourites for the Ashes.

But despite everything that has happened in recent weeks, Lehmann -- who took charge with immediate effect ahead of the tour match against Somerset -- was in bullish mood when asked if Australia could still regain the Ashes.

"Yes definitely, It is a challenge for all the playing group and everyone involved with Cricket Australia. We are going to play an aggressive brand of cricket that entertains people and fans and gets the job done on and off the field,” Lehmann said.
